PORTABLE STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 237,181, dated February 1, 1881.

Application filed October 1, 1879.

To all whom it may concern:

Be it known that we, JONATHAN HALL and O. MAROELLUS LANE, of Keene, county of Cheshire, State of New Hampshire, havej ointly invented new and useful Improvements in Portable Steam-Engines; and we do hereby declare that the following is a full, clear, and exact description of our invention, enabling others skilled in the industry to make and use the same, reference beinghad to the accompanyin g drawings, forming a part of this specification, and to the letters and figures of reference marked thereon.

The obj ect of our invention is to provide portable steam-engines which are cheaply built, and. although being connected to the steamboiler or steam-generator, are supported by and attached to independent rests or standards for the boiler proper, and do not derive any support whatever from the boiler, although they both may be moved and transported together.

In order to clearly describe our invention, it will be necessary to describe, briefly, the construction of theportable steam-boilers to which our improved steam-engines are best adapted.

The steam-generators are constructed of a cast-iron fire-box and a combined back-rest and smoke-stack base, which are connected together by aid of a semi-cylinder, which forms the cradle or receiver for the steam-generator proper.

In order to more fully'describe our invention we refer to the drawings, in which Figure I is a side view of our improved portable engine connected with a portable steam-boiler, as above described, showing the cylinder and its attachments. Fig. III is another side view, showing the fly or band wheel and its connections; and Fig. II is a back view of the same.

the guard O is also bolted as well to the standard A as to the cylinder B or they maybe cast in one piece, as may be preferred. This guard O is formed horseshoe shape, and has the open ends extended far backward, where it meets and is attached to cylinder B. The guard is so arranged as that the journal-bearin gs sh all find a lodgment in the broad curved end thereof, and its sides run down the side of the boiler and entirely protect the connect- 6o ing-rod and the race.

On the opposite side of the steam-generator is the standard or rest D, which is bolted to the back-rest of the hereinbefore-describcd portable steam-generator. vided at the rear end with a large bulge, which nearly corresponds to the guard on the opposite side, and furnishes a rest for the journalbearing on this side and allows the shaft to pass through it.

To the back part of the standards A and D are bolted the journals a and b, in which is placed the axle 0, provided at one end with a crank, d, and at the other end with a fly or The rest D is proband wheel, E. The connecting-rod e is connected with the crank (l, and thus gives motion to the axle c and the fly or band wheel E. e is the slide-rest for the piston-rod. By this arrangement the crank and connecting-rod, as

well as the slide-rests and the piston-rods, are So all placed within the guard O, and are thus protected from injuring themselves or causing injury-an evil to which all unprotected moving parts of an engine are liable.

It will also be seen that the parts are so arranged that the cylinder cannot come out of line with the crank-axle, and that the engine is not influenced by expansion or contraction of the steam-boiler.

We are aware that portable steam-engines 0 have the same means of attaching the stand- 5 ards to the boiler which ours has, which at once secure the utmost strength and greatest facility of detachment.

' The above-described framing possesses advantages peculiar to itself. In extending above 1 oo the working parts of the engine it furnishes a protection for said parts which will defend them against all accidental blows and ward of persons or things. This naturally tends to preserve and keep in good working order these parts, and at the same time, to a great degree, prevents accidents to attendants and others about the engine. The shape of the guard O and rest D at their rear ends, and the adaptation they present for supporting journal-boxes, make a very firm framing.

What we claim is-- The combination of the movable framing for portable steam-engines herein described, consisting of the standard A, supporting the cyl- 15 inder B, the guard G, formed in the shape of a horseshoe with extended sides, and arranged to afford a rest for the journal-bearing at its rear end, and the standard D, provided with the broad swell at its rear end, affording a rest 20 JONATHAN HALL.
